Serum paraoxonase (PON1) is a high-density lipoprotein (HDL)-associated enzyme that protects lipoproteins, both low-density lipoprotein (LDL) and HDL, against oxidation, and is considered as an antioxidative/anti-inflammatory component of HDL. In this study, PON1 was purified from bovine serum by ammonium sulfate precipitation and hydrophobic interaction chromatography on sepharose-4B-L-tyrosine-1-napthylamine. It was then immobilized on an unmodified Eupergit (R) C 250 L support. The immobilized PON1 retained a high catalytic activity and showed increased thermal stability compared to the native enzyme.
